Sambusak (סמבוסק) is the half-moon filled pastry of the Iraqi and broader Mizrahi-Sephardi kitchen in Israel: a short, semolina-rich dough folded around a savory filling and crimped at the edge, eaten as a hand-held stuffed pastry. It earns its place among sandwiches as a sealed bread-and-filling pocket. The angle is the dough. Unlike the airy pita or the laffa wrap, sambusak's casing is a tender, slightly crumbly semolina pastry made to be the structural and flavor partner of the filling, not a neutral carrier, so the order hinges on the dough being short and rich without going greasy.
The build is dough and filling, sealed. The dough is worked from semolina or a semolina-flour blend with oil and water until pliable, rolled into rounds, filled, folded into a half-moon, and crimped along the curved edge so nothing leaks. The classic fillings are two: a cheese version, often a salty grated white cheese sometimes mixed with egg, and a meat or chickpea version, a spiced ground meat with onion or a seasoned mashed chickpea with cumin and parsley. It is then baked or deep-fried. Done right, the pastry is tender and short with a clean snap, sealed tightly so the filling stays put, the cheese melts to a salty stretch or the meat and chickpea stay moist and well-spiced. Done wrong, the dough is tough or raw at the thick crimped seam, the casing is oil-logged from a slack fry, or the pastry splits and the filling weeps out into a greasy mess.
It is usually smaller than a burekas and eaten out of hand, often with pickles, amba, s'chug, or a squeeze of lemon, and sometimes tucked whole into pita as a filling in its own right. It varies first by the filling, a cheese sambusak leaning salty and rich, a meat one leaning savory and spiced, a chickpea one leaning earthy and lighter, and second by the cooking, a baked version leaning dry and bread-like, a fried one leaning crisp and indulgent. Burekas and other Mizrahi filled pastries sit in adjacent territory as forms of their own. Each deserves its own treatment rather than a line here, but they all return to the same idea: a short semolina dough built to partner its filling, crimped tight so the pocket holds.
